	uint32_t offset;

*SysCommParser by TizzyT http://tizzyt-archive.blogspot.com.es/2015/02/syscommparser.html

==Log Info==

Each of the times a request is made that involves Auth1+Auth2,there is a communication made to eeprom for read/write. It goes like this (case for backup_srh):

* Read initial 16 bytes of eeprom once (packet 0) (0x10)
* Read 32 bytes following  20 times (packets 1-21) (0x280)
* Auth1 established
* Repeat steps 1 2
* Auth2 established
* Repeat steps 1 2 for finding key?/validation?
* Validation/Finding Key established
* Final Packet(s): Read EEPROM Location/Write to EEPROM Location/Do Other Tasks 

Notes:
* Initial bytes are constant and never change from phat to phat
* Following bytes are perconsole (EID1 most likely)
* Steps that don't involve sc auth1 auth2 such as reading eeprom using nvs service or checking syscon status (probably stored in RAM, because true value is in EEPROM encrypted) have no packet activity
